Pressure--enhanced fractional Chern insulators in moiré transition metal dichalcogenides along a magic line

Nicolás Morales-Durán, Jie Wang, Gabriel R. Schleder +5

We show that pressure applied to twisted WSe${}_2$ can enhance the many-body gap and region of stability of a fractional Chern insulator at filling $\nu =1/3$. Our results are based on…
